For learning sqlite I have created simple step by step Tutorial with sample code Let! me try to answer your all questions one by oneġ.The below line NSString *sqLiteDb = saying we will create banklist.sqlite3 file for storing our database.Ģ.we use the sqlite database, whenever we need to store application's info locally, it can be your choice.ģ. It's a little more complicated, but has some advantages. There can be compelling reasons to use SQLite (via FMDB, for example), but Apple engineered the rich Core Data framework that has some advantages for iOS-only apps. And I'd be remiss if I didn't note the Core Data is the preferred database technology for iOS development. You didn't ask, but if you're starting SQLite development, using FMDB can greatly simplify your Objective-C code. I think a lot of people use a FireFox SQLite Manager tool The sqlite3 program available in the Terminal command line interface. But there are lots of Mac tools that you use during development. I don't think there are iOS tools (as apps keep their files (and a database is just a type of file) in their respective sandboxes and thus one app can't open a database in another app's Documents folder). Is there any free tool is available in iOS to read these database files If you go through the various tutorials you find, they'll walk you through or approach or the other. Then, programmatically you check to see if database already exists in the Documents folder and, if not, copy from the bundle to Documents folder (if you do this, you might want to use sqlite3_open_v2 with the SQLITE_OPEN_READWRITE option, but not the SQLITE_OPEN_CREATE option, so the database won't be created if it's not found) orĬreate database programmatically by (a) check to see if it exists in Documents and if not, create database (with either sqlite3_open_v2 with the SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE options or just sqlite3_open (which uses those two options by default)) and then execute the SQL CREATE statements or (b) if it already exists in the Documents folder, just use it. The general process is either:Ĭreate database on your mac and include it in the project and the resulting bundle. It's the same sort of file, just a different extension. You open databases (i.e., a file, conventionally with either db or sqlite extension) the same way. How can i open the db file and sqlite file You should always copy database from bundle to Documents folder first, before opening the database in the Documents folder. My only criticism of that tutorial is that I don't like the fact that he's open a database from the bundle. I generally like Ray Wenderlich tutorials and his SQLite tutorial is here: SQLite 101 for iPhone Developers: Making Our App. Both sqlite (without the 3) and db are commonly used.Ĭan you also provide me some good links to learn the database for the iOS Can you please tell me where we will use the sqlite3 and where db
